You can certainly automate crossfaded audio between multiple sources to try to get the cleanest copy, but it's hard. For instance, how do you decide whether it's noise or the letter "s" or the "chk" of a pick across muted guitar strings? The heuristics for "better than any constitutent audio source" can be extremely nuanced, algorithmically intensive, and still difficult to pin down, akin to speech recognition. Speak…

I don't know anything about audio processing algorithms, but (assuming there's a way), presumably with enough audio sources, there'd be a commonality between each one that describes the 'correct' sound. I.e. if there's different noise going on in each source (people talking around each microphone, at a gig, intermittently), you don't really need to decide which sound is 'clean' because you'd know which sounds are inc…

Sure, but it's determining what is "correct" that is the hard part. You could use a majority-rule if you have three or more sources, but the more additional sources are required starts getting into pretty niche territory and it still remains possible that the minority source is the most faithful one.

Very impressive. Very cool. I assume this will eventually extend beyond concerts to all kinds of other live events (sports, plays, etc). This is going to be big.

What's also interesting is how much the effect of SOPA will have on such an awesome service like this. So disappointing to think about how the copyright holders would rather shut you down then come up with a great way to enhance the service and share revenue with you.

Best of Luck. We'll all be rooting for you guys.

This is awesome. My only suggestion is to allow the user to switch angles without changing the audio track. Since these are concerts, the audio track is going to be one of the most important things. Often times one video will have significantly better audio than the other ones. It'd be nice to be able to choose that one to stay constant. Alternately, it'd be awesome if there were a way for the bands themselves to upload the recorded concert audio.

I realize that often times getting the recorded audio for a concert can be a finicky matter, but maybe you could partner with one of the many music festivals that are cropping up to make it happen.

Courts ruling on fair use are supposed to take into account "the amount and substantiality of the portion used in relation to the copyrighted work as a whole". Automated copyright detection schemes in YouTube may try to do some semblance of fair use by allowing snippets of copyrighted content under 30 seconds.

just a sidenote - if bittorrent software ensure that no peer-to-peer interaction exceeds 30 sec. for any given title, would MPAA/RIAA/etc... still be able to claim "illegal dowload"?

No, the courts take context into account. So for example, it might be perfectly legal to post 2 sentences from a book on your blog, if 10,000 blog posters conspired to post a different 2 sentences to share the whole book, that would be clearly illegal. Furthermore, the law is interpreted by Judges, who are people, not machines, and they tend to take a very harsh stance against people who try to game the system.

Site seems to be struggling under load. I am excited about the concept - was thinking about this very idea while watching Coachella streaming live this year and then seeing all the cams people were uploading.

Even using that, all I get are Internal Service Errors...

I wonder how possible it would be both technically and legally to use the audio from the various angles as inputs into an audio processing step where you distill just the true music audio and clean it up. Ideally you'd have one 'cleaned' version of the audio playing and switching views just switches video. This may be more legally grey than just piping through audio since you are actually producing a derivative work…

It would probably be technically "possible" but I doubt that you'd end up with anything that sounds listenable. The only bootleg audio that usually sounds decent are soundboard recordings, and when you find audience tapes spliced in with them the difference is immediately noticable.

I think theoretically you can make it quite good, but it's not going to be a simple task and you probably can't rely on purely the fans' recording. I think the best way would be to modulate them together based on a weighting depending on position or distance away from where the music is coming from, also discarding distorted recordings etc. That said, you probably only want this lightly mixed in along with a good recording from the desk, all adjusted for the viewing angle.

This certainly looks like a tortuous infringement in the UK (and I'd posit Europe). I didn't get a "only in the US" notice on YouTube though. I can't see how this is possibly "fair use" - it's the complete work of music and the visual design of the set, choreography and show that is being reproduced in full in a commercial way. Unless the uploaders bought a license with their ticket to reproduce and distribute online…

It's an embed. Supposed rights holders can easily contact Youtube with a DMCA request and they will take it down. What is the problem exactly?

>Supposed rights holders can easily contact Youtube with a DMCA request and they will take it down. //

This is largely irrelevant to the question of infringement and puts the onus on the owner to spot those infringing. Just because there's a ready way in which you can complain doesn't mean that the unlawful activity is somehow made lawful.

Note I'm making no comment here wrt the soundness or morality of said law.
